This is an example of content type header,

“Content-type: text/html; charset=iso-8859-1?

So what is this for? from the RFC 2616, you could get the explanation:

When an entity-body is included with a message, the data type of that
body is determined via the header fields Content-Type and Content-
Encoding. These define a two-layer, ordered encoding model:

entity-body := Content-Encoding( Content-Type( data ) )

Content-Type specifies the media type of the underlying data.
Content-Encoding may be used to indicate any additional content codings applied to the data, usually for the purpose of data compression, that are a property of the requested resource. There is no default encoding.
Any HTTP/1.1 message containing an entity-body should include a Content-Type header field defining the media type of that body.

There are many content management system (CMS) web wares on the net. What i/we love most is the Free and Open Source? why? tons of answers are available. How to choose from that abundant resources of CMSes? here’s the guide:

• If you want to use CMS that is suitable for big enterprise that has to deal with large amount of contents, than i think you have to choose Joomla or Mambo. Although it’s a little bit heavy but for i guess it’s very suitable for big enterprise. I consider Joomla or Mambo is a heavy duty CMS.
• For medium class, i think you should use Drupal. It’s also full featured CMS, many plugins are available.
• For light weight CMSes, you could use Wordpress/serendipity or b2cafelog. It’s easy to operate although the customization is not as flexible as two previous classes.
